Parallel Plate Electrochemical Reactor Model: Material Balance Closure and a Simplification

Parallel Plate Electrochemical Reactor Model

A model is presented for a parallel plate electrochemical reactor which has electrodes that are the same size and are close together. That is, the distance between the electrodes (S) is much smaller than the length (L) or width (W) of the electrodes. Consideration of the material balance equations in light of this small aspect ratio (S/L) condit ion leads to predict ions of derived quanti t ies...

Dynamic simulation of a parallel-plate electrochemical ̄uorination reactor

A time-dependent mathematical model of a parallel-plate reactor was developed to study the electrochemical ̄uorination of organic compounds dissolved in anhydrous hydrogen ̄uoride. The model incorporates two-phase ̄ow with di€erential material, energy and pressure balances. Dynamic results are presented that show the e€ect of disturbances to the whole reactor or one of the cells of the multicell ...

Implementation in Parallel-Plate Electrochemical Reactor and Backward-Facing Step Geometries

A finite-difference method for predicting the current-density distribution in multi-ion electrolytes was developed, then implemented to actual experimental systems and compared with other numerical methods, analytic solutions for limiting conditions, and experimental measurements in order to be tested. The method accounted for diffusion, ionic migration, laminar convection, and heterogeneous el...

A Closed Loop Approach to Tank Reactor Model Simplification

Stirred tank reactors are widely used in the chemical process industry and in many of them there are problems and constraints related to the temperature control. In order to achieve a model suitable for temperature control of such a system a number of ad hoc assumptions and approximations are generally made. Here, a method to systematically evaluate the validity of such simplifications based on...
